Basic signal question(s)

Hi all,
Only this week I have started to try to pay attention to the signals.
The website https://signals.jovet.net/ is a great help
At the moment I am doing a Granger Heartland UP Scenario. I passed several diverging dwarf signals that made perfectly sense. but now are at . . . .

Which should mean . . .

So I stop and wait and wait and wait , finally try tab , and wait and wait . . . .
Now what is wrong with the way I am thinking ?
